Cycloneritida
Cycloneritida (nerites and false-limpets) is an order of land snails, freshwater snails, and sea snails.MolluscaBase eds. (2020). MolluscaBase. Cycloneritida. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=1054475 on 2020-08-21 These are gastropod molluscs within the subclass Neritimorpha. 14 of the families in the order are extant, and eight of the families are extinct. It was previously categorized as the clade Cycloneritimorpha. According to the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), as well as the Cycloneritida, the subclass Neritimorpha also contains the (entirely fossil) clade Cyrtoneritimorpha, plus a number of other fossil families that are currently unassigned. The earliest evolutionary forms of Cycloneritimorpha show double visceral organs, double gills, and normally a double-chambered heart. Taxonomy The taxonomy of Cycloneritida is based on work by Kano et al. (2002) that recognizes 4 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocenidae
Hydrocenidae is a taxonomic family of minute land snails or cave snails with an operculum, terrestrial gastropod mollusks or micromollusks in the clade Cycloneritimorpha. Hydrocenidae are widespread across the Palearctis and Africa, but reach their highest diversity in the Oriental, Australian, and Oceanian regions. The family is poorly known and has not been revised in the past 140 years and as a consequence, the status of the various genus names (including ''Georissa'') is uncertain. Hydrocenidae is the only family in the superfamily Hydrocenoidea. This family has no subfamilies according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005. Description The animal have no gill, but a pulmonary cavity. Tentacles are short and large. The eyes are prominent, situated at the upper or outer base of the tentacles. The foot is short, oval and obtuse. The denticle (tiny teeth) of radula have the formula ∞ 1, (1 + 1 + 1), 1 ∞. The central denticles are small and el ...
